Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inductive power transfer systems face challenges in maintaining optimal coil separation due to varying physical distances between mounting surfaces, which can lead to inefficient power transfer or circuit damage.
Innovation Solution
A mount with a base, cavity, and securing mechanism allows the inductive power transfer coil housing to be adjusted in height and secured, ensuring the coils are within the desired 8-14 mm separation range, using a resilient sleeve and clamp system for precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If transmitter and receiver coils are mounted to different components with fixed mounting surfaces, then the mounting structure is simple, but the coil separation distance cannot be controlled within the required IPT working range
Solution Approach 1:
The mounting structure incorporates an adjustable mechanism that allows the coil assembly to be positioned at variable distances from the mounting surface. The housing can be moved along the mounting surface within a range, enabling dynamic adjustment of coil separation distance to achieve optimal IPT working range while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the physical distance between mounting surfaces varies depending on application, then the system has high adaptability, but the coil separation cannot be maintained within desired range
Solution Approach 1:
The adjustable mounting mechanism allows the coil housing to be positioned at different distances from the mounting surface, adapting to various physical distances between mounting surfaces while maintaining precise control over coil separation distance within the required IPT working range.
Solution Approach 2:
The system changes the positional parameter of the coil assembly by allowing movement along the mounting surface, thereby adapting to different mounting surface distances while maintaining optimal coil separation for power transfer.
3Reliability
If coil separation is not controlled within desired range, then the mounting is simple, but power transfer efficiency decreases or circuit damage occurs
Solution Approach 1:
The adjustable mounting mechanism provides controlled movement of the coil assembly to achieve and maintain the desired separation range, ensuring reliable power transfer efficiency while using a relatively simple mechanical adjustment system rather than complex electronic control.
